Keeping Diesel Engine Warm
My dodge dually Cummins engine is very hard to start when cold. At home or camping with hookups I can plug in the block heater but what can be done when boondocking.

I seriously doubt that a dead grill heater is going to stop the truck from starting in 40-50 degree weather. I never let mine warm up and the truck starts fine in much colder temps than 40 degrees. There are other issues at work.
My guess is what was mentioned earlier about the MAP sensor. Although I bought my 2001 Cummins with a K&N air filter, which has since been replaced, and had no starting issues. Since your Cummins is a common rail engine, you might check fuel pressure specs.
